1. Since you are allegedly educated, why not explain what those products have to do with killing trees. And even assuming they do, why not trim the trees instead of chopping them down. The trimmings will provide whatever byproducts are necessary, and the tree will continue to grow and produce more.
2. Toothpaste can be made with inorganic chemicals, too. Furthermore, the fact that chopping up trees yields some benefits does not mean that civilized life cannot continue without lumber. Wood is good for a lot of things. You can make pianos and violins from it. But that doesn’t make its production essential.
3. If my house is made out of plastic, I can order whatever color of plastic timber I need, and it can be as strong as steel and lighter than wood, as well as water proof.
4. Getting oneself educated means asking questions of those who claim to know. At worst, they either won’t answer you, or will show their own ignorance. At best, you will learn something, even if not what was expected. See #1.
One part of getting educated is to learn by ones self.
Since you seem to have the ability to use the internet, simply do a search “Things made from wood” and learn for yourself.
You can no longer survive without wood and things made from wood products than you can without eating..OH WAIT, lots of foods have wood products within them.
So you wont be able to even feed yourself without wood.
It is the ONLY, ONLY, ONLY, completely renewable resource.
Get yourself educated.
